Fallout Chems as D&D Potions

Last game session, part of the loot recovered after a dangerous three-way battle (PCs, orks, and a wyvern) consisted of stimpacks, a staple of the Fallout series. Although the concept and delivery differ, the stimpack's function is identical to that of the healing potion: consumable instant healing that anyone can use. All of the Fallout chems work this way, and if you ignore the side effects, it isn't hard to find D&D equivalents.

Buffout grants the effects of a Potion of Bull's Strength and a Potion of Bear's Endurance.Jet functions like a Potion of Haste.Med-X functions like a Potion of Stoneskin.Mentats grant the effects of a Potion of Fox's Cunning and a Potion of Owl's Wisdom.Psycho functions like a Potion of Rage.Rad Away functions as a Potion of Neutralize Poison, except it cancels the effects of radiation poisoning.Stimpacks function like a Potion of Cure Light Wounds.Super Stimpacks function like a Potion of Cure Serious Wounds.Ultra Stimpacks function like a Potion of Regeneration.

Rad-X is the only common chem for which I can't find a close equivalent. Until I think of a direct comparison, we'll say it grants a +5 bonus to fortitude saves vs. radiation poisoning.
